Continental weathering as the source of iron in Jurassic iron oolites from Switzerland
Swiss Journal of Geosciences, 2023 Iron is extremely insoluble in oxic seawater. The lack of a large aqueous reservoir means that sediments rich in authigenic iron are rare in the modern ocean.

A Quality Control Assay to Access the HCl Molarity of Radionuclide Solutions
Chemosensors, 2016 Strontium-82 is produced by proton activation of a rubidium chloride target in an accelerator or cyclotron and purified by ion exchange chromatography. The Strontrium-82 is used in Cardigen generators to produce Rubidium-82 for cardiac imaging.

Strontium isotopes in Early Jurassic seawater
Geochimica et Cosmochimica Acta, 1994 Abstract The analysis of well-preserved, well-dated belemnites and oysters from the Jurassic of Great Britain has resulted in a well-constrained, detailed seawater strontium isotope curve for the Early Jurassic. The preservation of fossil low-Mg calcite was monitored using Mn, Fe, δ 13 C , and δ 18 O .

Chemostratigraphy of the Pliensbachian, Puesto Araya Formation (Neuquén Basin, Argentina)
Geologica Acta, 2005 In a preliminary attempt to establish an isotope stratigraphy, strontium, carbon and oxygen isotope ratios were determined from marine biogenic carbonates of Pliensbachian age, in the context of scheme of local ammonite Zones correlatable to the European

Variation of strontium isotopes in tektites [PDF]
Geochimica et Cosmochimica Acta, 1964 Abstract The rubidium, strontium, and strontium isotopic compositions have been determined in tektites from Indo-China, Philippine Islands, Java, Australia, Texas, Georgia, Massachusetts and Czechoslovakia. The range of Sr 87 Sr 86 ratios in 18 tektites is from 0.7121 to 0.7223, indicating the results of Pinson et al.
